Organiza

My research interests include the areas of computational biology as well as of bioinformatics with a strong focus on applications in molecular biology and medicine. I am leading the SysBioLab@UAlg. We are actively developing tools and databases to facilitate other researchers advanced investigations into complex molecular mechanisms. Ultimately, our goal is the construction of computational models bridging the various levels between elementary molecular processes and their physiological manifestations. For that, an in-depth knowledge of gene expression and its regulation, protein function and interaction and cellular systems and their control is required. Thus, current pivotal lines of investigation in our research group are:

1. Gene Expression Analysis

System-wide measurements of gene expression by microarray or next-generation sequencing technology have given us detailed pictures of the dynamical states of cells. However, the large amounts of generated data pose formidable challenges. For instance, it is well know that single transcriptome measurements can be sensitive to artefacts caused to the use of specific protocols and platforms. Meta-analysis can alleviate this problem and reveal robust and potentially more reliable expression patterns. We have therefore developed software platforms for query and interactive analysis of integrated expression data that have been obtained in diverse experiments. Furthermore, we have therefore developed new methods for improved data pre-processing and robust detection of transcriptional patterns and regulatory motifs. To optimize utilization of gene expression data, we also work on its integration with complementary types of data and information. Such approaches will give us to new insights into the complex regulatory mechanisms inside cells.

2. Molecular Interaction Networks

Proteins are essential for various processes in cells. Most functions, however, are performed by individual proteins alone, but by the coordinated action of multiple proteins. Understanding the functions of a protein, thus, requires the knowledge of its various interactions to other proteins. To set the groundwork for future studies, we have started to integrate various molecular interaction maps and established several publicly accessible resources for network-oriented investigations such as the Unified Human Interactome (UniHI), StemCellNet, and HDNetDB. In cooperation with other research groups, we utilize these resources, for instance, to detect changes of network structures during disease development and to identify novel molecular targets for therapies.

3. Systems Biology

Systems biology aims to capture the properties of biological systems that emerge from the complex interplay of the single components. Following this direction, we are studying the structure and function of regulatory and signalling networks for different biological processes. For this purpose, we combine comprehensive experimental profiling methods such as next-generation sequencing with in silico reverse engineering. The aim is to gain deeper insights into the dynamics of molecular systems as well as testable models for further experimental validation.

StemChecker - in silico screening for stemness signatures

Description

…

StemChecker is a web-based tool that enables researchers to rapidly check whether a given list of genes can be linked to stemness. For this purpose, we curated numerous published stemness signatures derived by alternative approaches. StemChecker examines whether genes uploaded by the user are included in the curated set of stemness signatures and evaluates the statistical significance. The results are displayed in alternative formats, showing the potential association with stemness signatures of individual genes, as well as of the whole set of inputted genes. Additionally, StemChecker indicates whether genes are targeted by a set of transcription factors linked to pluripotency and stem cell maintenance.

StemCellNet - molecular networks in stem cells

Description

…

StemCellNet is an interactive web server for network analysis and visualization in stem cell biology. It gives access to a large collection of curated physical and regulatory interactions identified in human and murine stem cells and features various easy-to-use tools for selection and prioritization of network components, as well as for integration of expression data. StemCellNet can indicate novel candidate genes by evaluating their connectivity patterns. It is the only current platform, which allows the screening of networks for stemness-associated genes and potential target candidates. With its comprehensive coverage of the human interactome, it is a powerful tool not only for stem cell researchers, but also for researchers working on degenerative diseases and on cancer to identify stemness signatures in molecular networks of interest.
